WELLESLEY R. HAMPDEN, OF KANSAS CITY, MISSOURI, ASSIGNOR, BY DIRECT AND MESNE ASSIGNMENTS, TO THE FUEL SAVER HEATING COMPANY, A CORPORATION OF MISSOURI.

HEATING-STOVE.

Specification of Letters Patent.

Patented Dec. 25, 1906.

To all whom, it may concern:

Be it known that I, IVELLEsLEY R. I'IAMP- DEN, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Heating-Stoves; of which the following is a specification.

This invention relates to heating-stoves; and my object is to produce a stove of this character of such construction that in operation a double combustion takes place, the first being that of the fuel and the second that of the gases which were liberated by the expansion of the fuel and unconsumed by the first combustion, it being well known that in all heating appliances a very large percentage of the fuel in the form of smoke and combustible gases escapes to the atmosphere and represents that much waste.

A further object is to produce a stove of this character of simple, strong, durable, and cheap construction and of any desired configuration and ornamentation.

To these ends the invention consists in certain novel and peculiar features of construction and organization, as hereinafter de scribed and claimed, and in order that it may be fully understood reference is to be had to the accompanying drawings, in which Figure 1 represents a central vertical section taken on the line I I of Fig. 2, part of the fire-pot appearing in elevation. Fig. 2 is an irregular section taken on the line II II of 3 5 Fig. 1. Fig. 3 is a horizontal section on the line III III of Fig. 1.

In the said drawings, 1 indicates the shell or body of a stove of any suitable or preferred type, the type illustrated being that known as the magazine-feed, the magazine 2 be ing frustum-shaped and depending from the top of the shell, the magazine being frustumshaped to guard against the chokage of the same due to the expansion of the fuel therein under heat.

3 indicates the usual pivoted cover-plate at the top of the magazine, and 4 the customary crest or crown piece, which maybe of any desired form.

5 and 5 indicate tubes projecting rearward by preference from the shell or body near its lower and upper ends, respectively, and 6 indicates the stovepipe connected by elbow 7 at its lower end to tube 5 and by an arm 8 to tube 5 the passage between the shell or body and the stovepipe by way of tube 5 and arm 8 beiir controlled by the damper 9 of the type siown or any other suitable or preferred type.

The stove is preferably mounted, as usual, on legs 10, and secured horizontally within the shell or body at a suitable distance above tube 5 is a skeleton partition in the form of a ring 11, provided with a plurality of com paratively large holes 12. i l

13 indicates the fire-pot of suitable configuration and disposed within and of somewhat smaller diameter than the shell or body and above the skeleton partition 11 and provided with an outwardly-projecting flange 14, resting upon said partition, said fire-pot being provided with a cylindrical ash-pit depending through the skeleton partition a suitable distance, so as to leave a space between it and the bottom of the shell or body. The ash-pit is provided with a horizontal hollow portion 16, which projects through the front side of the shell and is equipped with the usual door 17 of any suitable type, and fitting in the ash-pit is a removable ash-pan 18, having a handle 19, by which it can be conveniently slipped in or withdrawn from the ash-pit by way of said hollow portion 16.

20 indicates a tube in the form of a ring or annulus which snugly embraces the outer side of the fire-pot at its upper end, and said tube or annulus is provided with a plurality of downwardly-disposed jet-orifices 21 to tion-chamber 22, surrounding the fire-pot and ash-pit, the tube being provided with a plurality of radial intakes 23, which project through the wall of the shell or body and communicate with the atmosphere.

The intake-tubes are preferably spaced at equal distances apart and form asecure and reliable support for the tube 26 and the fire pot, the said tube snugly embracing the firepot and the under side of its flaring upper end.

In the practical operation of the stove the fuel is placed in the lire-pot and ignited in any suitable or preferred manner, the damper 9 and the ash-pit door or its usual slide (not shown) being opened in order that the draft may be up through the grate and fire discharge into the space or second combus pot and thence through tube 5 and arm 8 into the stovepipe 6, passing thence to the chimney. (Not shown.) As soon as the combustion is well under way the ash-pit door or its slide and the damper are closed, and as a result the direction which the products of combustion must follow is changed, the new course being as follows: over the fire-pot and down past the perforated annulus and in such passage drawing the air from the room through the intakes into said tube or annulus, through the orifices of the latter into said chamber, such air obviously supplying a large volume of oxygen to mix with the smoke and unconsumed gases arising from the burning fuel. This oxygen and said gases and smoke are thoroughly intermixed and commingled in the combustion-chamber 22 and produce a highly inflammable gas which instantly ignites and consumes such smoke and combustible gases, the flame and heat passing down through the skeleton partition and almost completely enveloping the sides of the fire-pot and the sides and bottom of the ash-pit, so as to superheat the same, and thus more efiectually expand the fuel contained therein and liberate all of the combustible gases of such fuel. After passing through'the skeleton partition the heat and flame pass through tube 5 and elbow 7 of the smoke-pipe 6 and escape to the chimney in the usual manner. In this operation it will be understood that after the fire is well started air is supplied only by way of the perforated air-ring or annulus, and consequently does not come into direct contact withthe fuel in the fire-pot, the draft to supply combustion in the latter being consequently a suctional one. It will thus be seen that combustion not only takes place in the fire-pot, but a separate and distinct combustion occurs in the combustion-chamber surrounding the fire-pot, this second combustion being so perfect and complete that no smoke is discharged from the chimney.

A heating agent of the construction described which consumes all of the smoke and combustible gases obviously can be operated far more economically than an ordinary stove having a single combustion.

From the above description it will be apparent that I have produced a heating-stove possessing the features of advantage enumerated as desirable and which obviously may be modified in its form, proportion, detail construction, and arrangement of the parts without departing from the principle and scope or'sacriiicing any of the advantages of the invention' Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is

A heating-stove, comprising a shell, a body portion having an open upper end, a frustum: shaped magazine depending through the open upper end, a fire-pot below the magazine and within and of smaller diameter than the shell or body portion and having a flared upper end, an ash-pit below the grate of the fire-pot and provided with a hollow portion projecting through the shell or body portion and provided with a door at its outer end, an ash-pan occupying said ash pit and adapted to be introduced therein or removed therefrom through said hollow portion, a stovepipe communicating with the shell or body portion above and below the fire-pot, a damper controlling the upper point of communication, a circular tube surrounding the firepot near and underlying its upper or flared end and provided at its outer side with jetorifices and with a plurality of intake-tubes 23 extending outwardly through the shell or body portion, and a skeleton partition supported within the shell or body portion above the lower point of communication therewith of the stovepipe and forming a support for the fire-pot, and all arranged substantially as and for the purpose described.

In testimony whereof I affix my signature in the presence of two witnesses.
